Everybody seems to like How To Links and How To Sites. If you are working online and run into a problem, you can almost always bet that you can find a solution on how to fix just about any problem by searching online.
Sometimes it's just a matter of going to YouTube for a short and to the point video tutorial, and for those that prefer to have written instructions, you can usually find a suitable step-by-step guide by searching the popular how-to-sites. Just find whatever you are looking for by typing a phrase or a couple of keywords related to your problem into Google, Bing, or Yahoo! Think of a couple of ways that other people may be searching for the same information.
The Q&A sites are great for this, too. These are great and free resources for people that work online and on the road. So this naturally includes digital nomads and other road warriors.
